Special effects on iPhone camera gone

I got my new iphone 4 from Koodo last week. I noticed when taking pictures there were 'effects' that I could do the pictures. Now however, they aren't there anymore... was it just a temporary extra? Do I have to download an app? Or can I just not find it anymore?

Im only on iOS 5 so Im not sure about iOS 6 but there are no effects on my stock iPhone camera or photo album.
Are you sure you were not using an app or even using facebook to upload the pic as they have options to do that
